Spring Transactions - 在未经检查的异常(RuntimeException)后防止回滚

Question

我无法阻止事务在 RuntimeException 之后回滚.
我的环境是在 Websphere 8.0 上运行的 Spring 4.1 + Hibernate 3.6 + JTA (WebSphereUowTransactionManager)。
“doStuff”案例:有效
首先，一个表现符合预期的简单案例。自从我捕获 RuntimeException ，事务提交，新资源创建成功。

@Service("fooService")
public class FooServiceImpl implements IFooService {

    @Transactional
    @Override
    public void doStuff(Resource res){
        authService.createResource(res, "ADMIN");
        try {
            throw new RuntimeException("SOMETHING");
        } catch (RuntimeException e) {
            e.printStackTrace();
        }
    }

“doStuff2”案例:有效
下一个也可以。我声明 noRollbackFor 让我们提交事务:

    @Transactional(noRollbackFor=RuntimeException.class)
    @Override
    public void doStuff2(Resource res){
        authService.createResource(res, "ADMIN");
        throw new RuntimeException("SOMETHING");
    }

“doStuff12”案例:不起作用
最后是有问题的。不同之处在于，在这种情况下，第二次调用 authService.createResource 会引发异常。 .仅供引用， authService.createResource仅标记为 @Transactional ，所以默认的传播配置适用，它应该加入调用服务的事务。

    @Transactional(noRollbackFor=RuntimeException.class)
    @Override
    public void doStuff12(Resource res){
        
        authService.createResource(res, "ADMIN");
        try{
            res.setName("EXISTING-RESOURCE");
            authService.createResource(res, "ADMIN");
        }catch(RuntimeException e){
            e.printStackTrace();
        }
    }

尽管 捕获 RuntimeException 并声明 noRollbackFor 属性事务总是回滚。有什么解释吗？？

Answer 1

据我所知，一旦从事务方法抛出运行时异常并被事务拦截器拦截，事务就会被标记为仅回滚。即使这个事务方法是从另一个事务方法调用的。

这对我来说很有意义:如果内部方法无法从异常中恢复，它就无法恢复，并且外部方法不应该像什么都没发生一样。

如果您希望事务不回滚，您可以

使内部方法成为非事务性的

配置内部方法不回滚此异常

有两个内部方法:

一个是事务性的，旨在在还没有事务时调用，它只是委托(delegate)给第二个

非事务性的，旨在作为现有事务的一部分调用
